2. Power Supply
2.1 Requirements
This RSSK is supplied with an E1 debugger or E2 Lite debugger. The debugger is able to power the RSSK
board with up to 200mA. When the RSSK is connected to another system, that system can supply power to
the RSSK. This board has an optional centre-positive supply connector using a 2.0mm barrel power jack.
This CPU board supports one external voltage input. Details of the external power supply connection are
shown in Table 2-1 and Table 2-2 below. The default power configuration is shown in bold, blue text.
